When does caliber start making a differants

So you have two bullets almost with the same BC and sectional density and Vel.. But one is a bigger caliber then the other one. When does it start to make a differants to what it hits. Does it show in a 30-06 and an 8mm with the same type of bullet or to have to have a bigger size differants to have it show up in the feild.

Caliber makes a difference only when the guy behind the rifle is capable of taking advantage of any increased level of performance. "Paper" ballistics are just numbers on a spread sheet unless the user has the nuts and bolts skill to put those figures to work in a practical way.

For example, the .340 Weatherby is obviously a much more potent round than the .308 Winchester is, but if a given shooter can't handle the recoil and shoot the big .340 with precision, he's likely to see better results out of .308. If he has practiced sufficiently and can shoot the .340 with reasonable skill however, he'll have an undeniable advantage working for him, especially when the animals run as large as elk, moose, and the big bears.

It's not the thunder that kills - it's the lightning!

P Dog: Didn't we sort of have this discussion?

Depends on what you are hunting, and didn't we sort of divide it into 223, as one class, around 308 as the next, and then, for some reason, the 338-375 class, next being the 400's, then the 500's, and, we don't want to talk about the BMG, and then the 577 and larger class?

Socrate glad to see you jump in on this one.
allen day so do you think it starts 3 calibers higher. But remember we are talking same vel bc and sectional des. Or so you have to have a corrisponding increase in vel to have it make a differants.

I am also reminded of the 4 bore story. That guy that built the 4 bore, lung and hearted a buff, and it still ran 60 yards.

I would also suggest then, that what you are shooting at may determine the effectiveness of the calibers, and, that they are all determined, as Allen said, by the hunter's ability to hit what he's aiming at.

I would rather have Saeed trying to kill a Cape buffalo with a 223, then me with a Vincent Buffalo stomper, or a 4 bore...

Let me add something to the 4 bore story. The individual that shot the 4 bore used a hard cast alloy slug which did not expand. It had a final diameter of about 0.94". My 505 and now my 500 AHR with soft points will both reliably expand to over 1.25" and up to 1.5". That is a significant difference in diameter over the 4 bore isn't it! The 4 bore does not penetrate as well as the 50 caliber does either. Finally the 50's are packing at least as much energy as the 4 bore! To me the old bore guns are all romantic hype. My Father had an 8 bore that didn't do much more damage than a modern 12 gauge 3" magnum slug.

I personally haven't hunted with too much variation between the 30 and 416 calibers so I cannot comment on the progression between them. There is a big difference between what a 416 Rigby with 350 gr @ 2800 fps can do to an animal when compared to a 180 gr @ 2750 fps from a 30-06. There is an even greater difference between the 416 Rigby loaded as before or with 400 grains softs at either 2400 or 2600 fps and a 50 caliber shooting 570 or 600 gr @ 2450 fps. The 50 is 200% more devasting. The Rigby is not nearly as much of a step up from the 30-06 as a 50 Magnum is from the Rigby.

Shooting solids on the other hand I haven't noticed as big a difference. With the solid you aim is to smash through heavy bone. This seems to be accomplished well with anything .416 or bigger.

Didn't somebody post a while back that the biggest percentage of African game shot by people who live there AND who know what they're doing and shooting their rifle of choice is shot with a 30-06? I'm not stating, I'm asking.

The difference between one caliber and another is, both theoretically and in real life, always a fact. Simple physics dictates this. This apart from the more difficult to determine aspects of caliber versus SD and so on.

The problem is that the great variations in the single instance of a shot makes it very difficult to determine a "real-life" difference. It's (almost) impossible to make two exactly the same shots on game in the wild.

Therefore an advantage of one caliber over another could only be measured by collecting large amounts of data. Even so, for one particular hunter, his experiences could be quite the opposite from the outcome of a strict statistical analysis.

I recently read a summary of a statistical analysis of the moose hunts on the property of a large forest company in Sweden. The number of used shots and distance traveled after the shot was recorded for over 8 800 moose during a period of 10 years. Used calibers ranged from 6,5x55 to 375 H&H.

Shots per moose varied from 1,16 (358 NM) to 1,83 (300 WM but only 27 counts). Distance traveled varied from 19 (again 358 NM) to 57 meters (8x57). Another interesting tid-bit was that the 6,5x55 had the same average for number of shots as the 30-06 (1,57) but a *shorter* distance traveled (43 versus 47 meters). But even in such a large amount of data you have other factors that come into play. I know some of the people that participated in these hunts and know that a large portion of the counts (over 200) for the 358 NM was one single hunter! His expertice will of course make a difference more significant than caliber.

So, to sum it up, if you would like to see a marked difference for your own hunting between one cartridge and another you would have to take a large step up in caliber and/or velocity provided that you could handle the rifle as well despite heavier recoil. And you would have to take a lot of game with both before you could be really sure of that difference.

Todd E what are you shooting your 500 into to recover the bullets.
What is poor or less penetration if a bullet goes thru the critter side to side or if you shoot it from the front and it makes it thru the lungs but not to the hams. do you really need a bullet that goes an extra 2 feet or one that makes it thru.
Is a expanded 1.25 bullet better than a nonexpanded 1.0 bullet given the same penetration.

The penetration test I conducted with the 500's have been done on living buffalo and bison. They will enter the head and make it to the hamms or out everytime. A 4 bore will not penetrate that far period! The 45 bore NE is a much better killer than a 4 bore hence the obselence of the 4 bore.

With regard to whether a 1.25" bullet produces a bigger wound channel than a .94" bullet...YES IT DOES! The twist rate is much greater with the 50 than a 4 bore too.

I have seen buffalo get up (the buffalo was knocked down believe it or not Ripley) after being hit in the head (bullet missed the brain pan) and complete fore to aft penetration with a 50 caliber rifle. Now how many Pdogs can do that? My statements are not theoretical BS spewed out to impress someone. This is real life experience and if you wish to believe that some 30, 8mm, 338, 375, or whatever is just as good or better than a true big bore so be it! I do not care. If you hunt enough dangerous game your belief system will prove out natures law of natrual selection.

The 375 is a minimum for good reason. It is marginal at best as are the other 30 - 9.3mm bores below it. It will kill as will a 303 British. It just takes the animal that much longer to die (unless the brain is scrambled). This time differential can be problematic when the critter decides he does not wish to die ALONE.

By the way, once you piss these big boys off they are much harder to put down. That is probably why many game departments use fully automatic FN FAL rifles.


One last note. You only truly need enough penetration to traumatize the vital organs. I was only attempting to provide my experience to your discussions. My experience unfortunately has almost exclusively been with large calibers. I to, believe it or not, am interested in learning if there is a noticeable difference between the calibers as you progress up the scale from 30 caliber to 416.

Now you are free to flame away on me.

Good post, Todd E. Its interesting to ask the "speed kills" mantra types if they would like their PH's to carry a .243 as a back up if they were hunting the mean, fangy stuff.

I would like to introduce the thought that a larger than necessary wound, for a vital area, into a not so vial area will produce better results.

The South Carolina study has similar date at http://ulfhere.freeyellow.com/ballistics/game_study.html

My own observations, on whitetail deer, are that the 7mm Rem mag and 30-06 are about the same and that the .358 Winchester has more effect. But the bullets are not at all alike with the smaller ones similar in SD and BC and the .358 bullets much less in SD and BC.

In theory I seems obvious that the bigger bullet will be more effective with the costs mentioned by John S plus more meat damage.

Todd on 2nd thought you still havn't andswer the question when does the caliber start to make a differants. The Question was posed to get your opinon if you read my post I have not give mine yet.
You jumped from 375 to 50 cal so is that the starting point. 13 cals up.
So a fully auto FN is the way to go 7.62x51. They most likely carry them against the two legged varmits not the four legged kind.

Pdog:

Caliber makes a difference when you want or need to move more weight. I don't wanna get into the nitty gritty yet, but basically the more weight the bigger the punch, the heavier the bullet, in a lot of cases, windage becomes less of a factor. You make a bigger hole which gives you a better chance of recovering game. Heavier bullets:caliber fly better than light bullets:caliber.

I'll leave it to you rum/vodka/cognac drinkin' cigar afficionado's to quibble over the details, I'm just stating the basic to-do's, hahah...

I'm kind of curious. If you miss your intended target area, does caliber even matter?

I'm wondering if no matter how big the bullet, on hippo, rhino, buffalo, or elephant, if you don't kill them, do you only piss them off?

Also, what is the point at which one feels comfortable with a caliber, or better, bullet weight, knowing that if you miss the vitals, the bullet has a chance of breaking a bone, and planting the animal?

Perhaps the question should not bet caliber, but bullet weight?

I did answer your question in my first post. There is a marked difference between the 30-06 and 416 Rigby. There is a huge difference between the 500 AHR / 505 Gibbs and the 416 Rigby.

I think everyone got uptight about my statement with regard to the 4 bore. At least that is the only thing I was questioned about. Lets see. I got questioned about penetration. I said the 4 bore did not penetrate as well as the 500's did. I got questioned about bullet diameter. I said the 4 bore had a hard cast alloy slug of .94" while the .500 soft points expand to 1.25".

The Rigby expands to about .75" with a soft point. With regard to penetration in my experience the 375 is not as good as a 30-40 Krag or 308 FMJ. The best penetrating round is a 410 solid at 2680 fps out of a 416 Rigby. Well that last statement excludes the 50 BMG.

Now I have provided my experience (at least some of it)and covered the big end pretty well. I would like some more insight into the performance of the medium bores.

One last note. The SDs and BCs of the various big bores I have shot vary with caliber sometimes significantly. I usually load to get the maximum out of the bullet available not necessarily the maximum out of the case. For instance the 505 Gibbs and 500 AHR are both capable of pushing 600 grains slugs well in excess of 2650 fps. I load my 500 AHR to 2400 fps because above this and the bullets begin to fail.

Socrates,
You can blow the heart and lungs out of a buffalo or bear for that matter and if he is pissed it won't hardly slow 'em down. In that case you must shatter a shoulder to turn the charge or, much better by far, the brain shot. The spine is typically an unlikely target when you are getting charged by a bovine *head is in the way), but is a possible target with a bear.

I hope I answered everyone's questions so I can sit back and learn about the medium bores.

Todd:
Thanks for the comments. If you had to smash the spine, or such, what would you feel the minimum in bullet weight is, and, what would be your favorites?

Todd: It's hard to believe that something at the weight of the 4 bore solid,nearly 3 or 4 times that of the 600 grain bullets you use in your 50's, and hard cast alloy,
at a reasonable velocity, would not penetrate better, considering it's diameter.

This really flys in the face of all my handgun experience, and many others, where given a pretty much constant velocity, the best increase in penetration comes by adding bullet weight, not caliber, or more velocity.

This with all bullets being Keith style, and cast very hard, with little chance of breaking up, or deforming.

However, as diameter does get to large, the optimum penetration is lost. For example, a 45 Colt is outdone in penetration by a 475 Linebaugh, but, the 500 can't generate enough speed to get the larger diameter bullet to penetrate furthur then the 475, and, you can't add enough bullet weight to get more penetration either.

Socrates,
I thought I made that clear.

I have never shot a 4 bore, but everything I have ever heard was that the 4 bore did not penetrate as well as a 450 NE. What I was actually told once was that the 4 bore performed penetration wise about the same as an 8 bore. I have experience with an 8 bore and it could not penetrate a rail road tie at 30 yards! That was if I remember correctly a 1300 grain slug and 320 grains of Fg! The frontal area is too great for the measly velocity you get. The bore guns are only good for about 1250 to 1500 fps. They produce so much smoke from a shot that you are literally blinded unless there is a good stiff breeze. In my experience a good 3" magnum 12 gauge was as good a penetrating round as the 8 bore. Now how many people would hunt dangerous game with a 1 3/8 ounce 3 in 12 gauge slug? Now I will add that we did not shoot wheel weights out of the 8 bore for fear of tearing up the old damascus steel barrel. We fired what we had been told they used in the days when that rifle was in use. That being paper patched lead! That stuff is soft.

The bore guns went away for a reason. They lacked penetration, they were too heavy, they produced awesome smoke screens, and finally the lighter Nitro guns outperformed them hands down.

I guess if you used straight antimony, or something like that, you might get far better penetration.
On the otherhand, you might not be able to overcome the bullet diameter, at that velocity, regardless of bullet material.

Intresting that you couldn't use harder materials... Never heard that one...

Todd E It would seem to me you are saying you have to increase caliber by 10 or so to start seeing much of a differants.
I lot of people seem to think that one or two thousands of a inch increase along with a 25 to 50 gr increase in bullet weight makes a lot of differants. IE the 338 and 375.
Bullet constrution seems to be more of a factor then a slight increase in weight and dia. Vel. also seems to play a large part the it you push them to fast they are not as reliaby. From a my own exspearince is that a heavy for cal bullet push in the 2200 to 2600 fps range give you the best prformance. as far as penetration goes.
Todd to stir the pot even more so the buff shot in the head and with complete penetration was this a bullet failure or caliber failure,bad shooting or just dam bad luck.
Bullet placement is always a very important part of putting any thing down for good.

Tood,


There you said the right words....

The bullets in your 500 expand to a bigger diameter than the 4-bore have....then it do bigger wound channels....

How big diameter do you think a 585 nyati can expand to whit 750 grain woodleigh soft nose bullets...?

I spoke to my own experience. There is a dramatic difference between each step i.e. 308 to 416 to 505/510. I have used Woodleighs almost exclusively for my big bore hunting rifles. I am interested in understanding subtle differences in performance in the progression of the medium bores.

As far as, the buffalo goes. I guess it was a bad shot. I missed the brain pan. The bullet struck the nasal area and punched through the pallet, into the neck muscle and through the thorasic and abdominal cavities before exiting through the pelvis between the legs! I would have to say that was damned good performance for both caliber and bullet, after all it made it through approximately 9 or 10 feet of buffalo. The buffalo was hurting pretty bad too. It was exhaling chunks of lung and liver the size of your hand and losing massive quantities of blood. His buddies surrounded him for a minute or so before I could put the finisher into him. They came over when he went down, one nudged him with its nose the others stood facing me with their asses toward the wounded one. Once the wounded buffalo got up they walked around him for 30 seconds or so and then the little party broke up and I got a second bead on his head, bang end of story.

If you haven't been over to Africa you really should go. If it is too expensive (I can understand that) the American Bison is relatively the same size (actually bigger in my opinion)and much more affordable. You can buld yourself a 500 and shoot one of these big boys and then you will know for sure and these nagging questions will no longer be there. I really wish Overkill would do this at least.

Socrates,
A knowledgeable old English gentlemen as I remember was the one who told my Father not to shoot hard cast or jacketed bullets in the 8 bore. Therefore, we shot the paper patched rounds. A single shot 8 bore shouldn't be too expensive to make. You could build yourself a muzzle loader and then you too could see how the 8 bore works first hand.

Thanks Todd, but I perfer to have others make such expensive mistakes;-)

I'm not doubting your word one bit, just pointing out it surprised me, and the reasons why.

I'm sure using soft lead, terrible penetration, in particular with such a large frontal area...

Socrates,

I agree the soft lead does tremendously reduce penetration. Again the bore guns were replaced for a reason. The 450 NE is no more powerful than a 458 Win Mag. The 450 NE is considered to be vastly superior to the 8 and even 4 bores. How many guys that post here give the 458 Win Mag any respect?

The bore guns are nice novelty items. I really believe though that you could get yourself a muzzle loader made up pretty cheap. Just think of the questions you would be asked at the range! Particularly after someone watches you pour 300+ grains of Fg powder down the pipe!

Todd, I'm nearly 50, and, I'm working my way up slowly. I've had a 30-06 for about 25 years, and, I'm close to adding a 375, if I can make a few more bucks.

Have the loaded rounds, with 270 grain softpoints, from federal sitting here, waiting for the rifle, and, I've got the dies and reloading presses, waiting to be setup.

While an 8 bore sounds intresting, I'm going to work up, little by little.

I also, find it weird that the 458 gets so little respect, yet, many people have, and use this caliber, and, report it kills very well.

I guess it's inability to push 500 grain bullets at 2400 fps make it the Rodney Dangerfield of big bore rifles. Weird.

Yet, it recoils too much for many, so they end up with a 416 or 375. Very strange.

I think perhaps the reason for the end of the big bores was not game performance, but recoil.

Can you imagine a 4 bore, or 8 bore, going off, with no modern day recoil pad?
How many broken shoulders did that produce, and, how many bad shots ended up in dead hunters, since, by the time the smoke clears, the elephant, or buffalo is 3 feet away, and mad as hell...

Socrates,

Actually I can. I fired my Father's 8 bore double the first time when I was 16. It kicked about like my Fathers's friend's 500 NE H&H Royale. The 8 bore weighed around 18 or 19 pounds if I recall. The 500 was I think around 11 pounds. My 505 Gibbs was a little stiffer in the recoil department. The 505 weighed about 10 pounds. The 8 bore sadly burned in a house fire back in 83 so it has been silenced forever.

Back in the late 60's and early/mid 70's these classic cannons were cheap as hell. I think the 8 bore went for about $1500, the 505 was $1200 and the 500 H&H was I think $3000. We made our own brass for the 8 bore by the way.

I was hopeing to get some medium bore defenders in on this. I agree with you fully if you go up 10 or so calibers you see a differants. Or have a substandal increase in bullet weight along with vel.
Todd I agree with you fully when you get up close and personal with one of the big ones and they don't like you a big gun is nice to have. I posted this to try and get some input for the fun of it and stir the pot. But no one else wants to play.
But it still comes down to proper shot place IE in to the vitals to make a quik killing shot. Then if you want to anchor them on the spot you have to break them down and a good size bullet works better for that.

In Haralds site on Terminal Ballistics I think the point is that if you make a hole of a certain volume it will cause a pressure drop in the blood supply that will incapacitate the animal.

He went on to say that this would define a rifle for non-dangerous game but that he felt that for dangerous game that hunters may never leave the big bores.

I read a comment once from a member from Denmark, perhaps it was here, who said that preditors have less of an ablity to deal with such shock.

To me the .45's are high kick and low hit. I don't have a use for one. If I was going to Africa for dangerous game I would rent one. I have owned them and to me they are not a lot of fun.

As you put it, there should be larger differences, if they should be percievable.

P Dog Shooter,
I think I know what's on your mind after reading the threads of recent weeks. It is my opinion that the attendent virtues of increased bore diameter are ignored, pretty much across-the-board, at our Forum. Sectional density #'s get the nod over a caliber increase, around these parts, whenever killing authority is discussed.

So, if a bullet is long and skinny, and, it peels back nicely, into a large diameter mushroom, doesn't the weight of the bullet, the mass of the lead, or whatever, determine quite a bit of about how large that mushroom is going to be?

While I am a caliber fan, in the minority here, it seems, doesn't a large mass, already larger, expanding bullet, expand to larger size then a small, skinny one?

In other words, if we took a 220 grain partition, in 308, and compare that to a
375 300 grain, expanding bullet, which is going to have the largest mushroom, and the greatest penetration?

Just for arguments sake, how about if we put the 308 bullet in a 30 inch RUM, at 3000 fps,
and, the 300 grain, in a 375 at 2600 fps?

And, for added comparision, move up to a 458 bullet at 2200 fps, soft point, or something like it, or all bullets partitions???

Then we can bring Todd in with his 505 Gibbs, and get a really giant hole, with an expanding bullet...

A investigation made by Stora forrest showed
that on moose 6,5*55,308,3006,8*57 7mm rm all have the same effect on moose about 1,35 shot/moose running about 50y.
300wm has a slightly better effect.
9,3*57,9,3*62 has much better effect, the mooses only run about 30y.
About 8000 mooses was in the test.
medium dist. 70y.

"Caliber makes a difference only when the guy behind the rifle is capable of taking advantage of any increased level of performance. "Paper" ballistics are just numbers on a spread sheet unless the user has the nuts and bolts skill to put those figures to work in a practical way." (quoted: from allen day).

I agree with "allen day" on this one. There are too many factors in determining which cartridge is "best." I have seen a moose drop with one shot through the heart, and if you watch the hunting video "Love Thunder And Bull II," you will see a moose taking one .416 shot at close range through the lungs, then the moose runs around the hunter and then drops with a second shot from the same gun. In this case at least, my friend with his .30-06 made a big difference.

I can believe that. I have always figured the 30-06 was supperior to a 416. This sounds alot like the question I asked on the Big Bore forum. Since many people cannot accurately shoot the big bores they are not as effective as the smaller medium bores.

Although I doubt that if that particular moose was shot with a 30-06 through the lungs he would have gone down as quickly as he did from the 416 hit. As long as both shots were made with soft points.

I once saw a moose take four hits in the chest and one in the jugular with a 338 Win Mag. Bullets used were 230 grain fail safes.
Which would have been better in this instance a 30-06 or a 416?

That's exactly why I agreed with "allen day's" first paragraph above. If a bullet (regardless of size) can penetrate enough to damage the heart, it may be possible for it to kill faster than another bullet (regardless of size) that hits a lesser vital spot. One of the guys at work uses a .308, and a few years back he got a bison tag by Delta Junction. He took his hunting partner along with a .375 H&H, and also his .308. He fired one time on the bison with his friend's .375 and hit it low on the neck injuring it, so he promptly grabbed the .308 and shot it through the heart killing it. He had no experience whatsoever with the .375, so he could not shoot it accurately, but with his .308 he is a crack shot.

In my example above (in my previous post) the difference was made when the smaller .30-06 bullet punctured the heart. The larger bullet from the .416 passed through the lungs missing the heart, so the moose had time to run around. It was probably half dead with the first shot, but still running. The guy was trying his .416 in Alaska before going to Africa.

Most of the moose I have killed have dropped with one shot from my .338WM. I use 230-grain FS bullets, and last year a 250-grain NOS. However, I learned to shoot moose with my hunting partners' help. At the beginning it was most difficult to learn the exact location of every vital organ, but once I did it was very easy to hit the right place. Since I am a meat hunter I only take shots through the heart or the center of the lungs. It means that I aim low on the chest so the bullet strikes right behind the shoulder bone. This shot will sometimes break one or both shoulder bones, and it will also hit the heart.

Have you watched Saeed's videos? If you do you will notice how fast the game he shoots drops when the bullet hits the right spot, and how much longer it takes if not. He uses a big wildcat, .375/404 I think.
